(b)(4).Device was used for treatment, not diagnosis.If information is obtained that was not available for the initial medwatch, a follow-up medwatch will be filed as appropriate.Investigation summary: the complaint device was received and visually inspected.Visual observations revealed the jaw to shaft pin was missing of its space contributing to the jaw failure.When the trigger was actuated, the jaws were not functioning as intended.A sample rubber strip was placed between the jaws and when the trigger was actuated, the jaws bite on the test strip with a small gap.An eiii needle was loaded into the device and was tested on a sample rubber strip.When the trigger was actuated, the needle deploys and restores it to the original position successfully.This complaint can be confirmed.Clamping excessive tissue between the jaws combined with repetitive twisting action exerts excess side load on the jaw pin resulting in the jaw pin falling off from its space.A possible root cause for the failure could be fair wear & tear due of the use of the device.The potential cause for this issue is not related to manufacturing, therefore a manufacturing record evaluation is not required.At this point in time, no corrective action is required, and no further action is warranted.Depuy mitek will continue to track any related complaints within this device family as a means of monitoring the extent with which this complaint is observed in the field.(b)(4).
